Blockchain-based finance platform Solv Protocol announced its plans to launch a structured yield vault for Bitcoin, aiming to unlock returns from idle Bitcoin (BTC) held by investors, valued at more than $1 trillion.
The new product, named BTC+ and capped at 400 BTC, offers institutional investors and crypto users exposure to yield strategies across decentralized, centralized and traditional financial markets. These include protocol staking, basis arbitrage and income from tokenized real-world assets.
Additionally, BTC+ targets an annual yield of 4.5% to 5.5%, with deposits and withdrawals allowed during the term, though early exits may result in forfeiting additional rewards.
According to the company, the vault uses a dual-layer structure separating custody from yield operations, and includes drawdown limits based on net asset value (NAV), a model commonly used in private equity. The vault also integrates Chainlink’s proof-of-reserves framework for on-chain verification of underlying assets.
Furthermore, the vault taps into both centralized and decentralized liquidity pools as part of Solv’s broader strategy to build Bitcoin-native financial infrastructure, with current holdings exceeding $2 billion in total value locked (TVL) as of August, according to data from DeFiLlama.
In addition to managing structured yield products, the company also operates as the asset manager for Binance’s BTC Earn product and is working with Avalanche on tokenized yield strategies. Furthermore, it is reportedly backed by Binance Labs, Blockchain Capital and OKX Ventures, and its infrastructure has been audited by Certik, Quantstamp and SlowMist.
BTC+ Joins Growing Field of Institutional Yield Products
Solv is not alone in targeting institutional-grade Bitcoin yield products. On May 1, 2025, Coinbase Asset Management launched the Coinbase Bitcoin Yield Fund, offering non-U.S. institutions access to a conservative cash-and-carry arbitrage strategy targeting annualized returns of 4% to 8% in bitcoin.
In parallel, XBTO has partnered with Arab Bank Switzerland to launch a branded Bitcoin yield product for high-net-worth clients. The product uses XBTO’s “Diamond Hands” options-based strategy, leveraging existing bitcoin holdings to generate premium income while gradually accumulating more BTC, with a target annual return of 5%.
More recently, Rootstock Labs launched Vaulted rBTC, an on-chain yield product backed by more than 500 BTC in reserves. The vault offers institutional and retail investors access to protocol-native returns across assets including bitcoin, stablecoins and RIF tokens.
